Actor Dwayne “The Rock” Johnson did something extra special for a young fan Saturday on the set of the new “Baywatch” film.

The Rock posted a video to Instagram showing the moment he presented a 7-year-old “cancer warrior” named “Tater” with his very own movie poster featuring himself.

Gabriel "Tater" Singleton has used an action figure of the wrestler-turned-movie star as his inspiration during his battle with cancer, WRCB-TV reported. So when Johnson invited him to the set of "Baywatch" in Savannah, Georgia, it was a dream come true.

Though the video doesn’t show Tater’s face, Johnson describes the event in great detail.

“When I told him ‘we're all so inspired by you, especially me’ and looked down at him and saw him lookin' up at me, nodding his head with those big eyes.. good Lord I almost lost it in front of him and the whole damn crew,” the “Baywatch” star confessed in a description of the video.

Johnson recalled another close call that happened one time when he was accepting an award. The actor caught a glimpse of his daughter Simone while thanking his family for their support and almost lost his cool.

“Despite my almost tearing up like a baby and ruining my tough guy image,” he continued, “the greatest and I think most beautiful irony about Tater, is that this very special little boy has no idea just how much he inspires all of us around him. One day he will.”

Watch:

The big moment where we surprised lil' 7yr old cancer warrior named "Tater" with his own #BAYWATCH movie poster! I wish you guys could've seen his face when I turned this frame around. When I told him "we're all so inspired by you, especially me" and looked down at him and saw him lookin' up at me, nodding his head with those big eyes.. good Lord I almost lost it in front of him and the whole damn crew. (that actually happened to me once before when I was accepting an award on stage and as I thanked my family, I just happened to catch my daughter Simone's eyes and sweet cheese on an ice cream sammich I almost lost it again). I did exactly what I did here.. paused, gazed into space like a crazy man and told myself "you better hold it together dammit", shook it off and proceeded to continue. Despite my almost tearing up like a baby and ruining my tough guy image, the greatest and I think most beautiful irony about Tater, is that this very special little boy has no idea just how much he inspires all of us around him. One day he will. #OnSet #OurWholeBaywatchCrew #UnforgettableMoment #LiveLikeTater #AndRocksDontCry * special thank you our good buddy and one of Hollywood's greatest photographers @jaimietrueblood and the @forthewinproject charity creating this awesome poster for Tater.

Earlier Saturday, Johnson posted another photo of him arm wrestling 7-year-old Tater, and apparently losing.

I can throw grown men into next week, but for some strange mystical reason I keep getting beat by kids at arm wrestling. Defeated by the powerful Tater in front of the whole crew. My ego can't take this. #OnSet #Baywatch #VerySpecialDay #VerySpecialLittleBoy #LiveLikeTater

Fans following The Rock and Tater's special day had plenty of praise for the father of two.

"You always choke me up when you do things like this for kids/people @therock your heart is pure," one fan commented.

“You’re amazing!” another wrote.

“Love this guy.”
